So we have:

- `locale` - store locale passed through to  ('en-US')
- `_pluralLocale` - Doesn't ever get set (Lines 87 and 205)
- `_pluralFunc` - Locale function used to normalize the count passed into `_normalizeCount`
- `pluralizeLocale` - transformed locale, if provided to lowercase and underscore ('en_us')

Is this correct?
